Abstract

See full text

A hemi-arthroplasty bone joint implant has a first part (120) with a stem (111) tor intramedullary implanting into a metacarpal, mid a second part (110) to engage the trapezium is a translational manner, a hemi-arthroplasty articulating coupling (121). This allows multi-axial motion with translational movement of the second part over the trapezium and rotation of the first part (110) about the articulating coupling (121, 103). There is also a converter to convert the implant to a total arthroplasty implant in situ during revision surgery. The second part (110) and the hemi-arthroplasty coupling (100, 123, 121) are removable in situ during revision surgery. The first part (120) has an engagement threaded socket (117) for, after removal of the second part and the hemi-arthroplasty coupling, engaging the replacement coupling (200) and allowing mutual articulation of the first (120) and replacement parts (220). This forms a total arthroplasty joint implant.
